We are delighted to see the return of House Martins again this year at Blisworth Hill Farm. These lovely birds have glossy blue-black upper parts and pure white under parts. They have a distinctive white rump with a forked tail. They spend much of their time on the wing collecting insect prey. Their carefully constructed mud nests can be seen under the eaves of the offices and we have up to 40 nests dotted around the Business Park. They are summer migrants and spend their winters in Africa. Although still numerous and widespread, recent moderate declines earn them a place on the Amber List.
